Verifying DMI Pool Data-error in MSDOS.SYS file

Hi can someone who is knowledgeable in these matters please tell me how to rectify error above. The rest of the error message goes on to say autoscan = 30013021330100000. After PC boots up this comes at the end of the screen. Having Windows Me I cannot edit the MSDOS.SYS file let alone find it. I am not sure but I think it may be the cause of starting and shutdown problems at times. I have had it for quite some time now having put up with it. TIA Cindylou
